| Abstract: | The micro-amplification imaging and image relative measurement are proposed based on CCD image technique. A measurement for geometric parameters (core diameter, outer diameter and non-roundness) of polymer optic fiber with an outer diameter of 1-mm or so is carried out through computer image processing. Its measuring accuracy is 6mm or so. The constitution and principle of the system are given. The measures for implementing the accuracy of the system are analyzed. The system can also be applied to measurement of numerical aperture of polymer optic fiber and characterization of the refractory index distribution. |
